 Stobbs Hill Pit, Lumley Colliery, below the thill

 Twizell, near Edmondsley, proving the thickness

 sunk from the surface to the Five Quarter Seam. 

 As walling was put in the shaft at the Grand

 as having been worked out hereabouts by this 

 period.

 of a coalfield underneath the overlying Magnesian

 coalfield until another twenty-five years or so
